23810282-1	2013	We have devised a procedure for the synthesis of analogs of combretastatin A-4 (CA-4) containing sulfur and selenium atoms as spacer groups between the aromatic rings.	Sulfur	97-103	carbonic anhydrase 4	Homo sapiens	80-84	
25937236-1	2015	By switching position of the N and S atom in the thiazole ring which were similar to the previously reported agent 5-(4-ethoxyphenyl)-4-(3",4",5"-trimethoxyphenyl)thiazol-2-amine, a series of 4,5-diarylthiazole derivatives were synthesized using Friedel-Crafts reaction based on chemical modification of Combrestatatin A-4 (CA-4).	Sulfur	35-36	carbonic anhydrase 4	Homo sapiens	304-322
